, To all whom ataxia concern:

. Allfth'e operating described and more "Be it States, residingatLakewood, in the' county of Cuyahoga and State of .Ohiofhave invented certain new and useful Improvements in Electric Call-Bells; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the. art to which it appertains to make and use thesame. Our invention relates. to improvements in electric call bellseand the improvement con sists ina construction and arrangement of parts, substantially as hereinafter shown and particularly pointed out intheclai ms. i I

The general object of the invention is to to be electricallyoperated froi'n diiierent distant stations or'places to produce difierent tones or sounds according to the station or place selected. Another object is to pro'vide a simplified consti'uction in which all the op; erating parts are contained within and completely covered by the bell;

In the accompanying drawings, Figure 1 is a sectional view centrally through the bell and its mounting andshowingthe electrical connection for the bell in diagrammatic form. Fig. 2 is a sectional viewon line 2-2, Fig. 1 showing the mounting alone and with the bell removed. Fig. 3 is a cross section on line '3-3, Fig.1.

provide a call bell constructed and; adapted Theinvention as thus shown comprises a base or'mounting 2 and armature 4- and hammer 5'--, contact making and breaking members -6} and Z,respectively, and bell '8- overall. parts and. the hell are mounted andsecured upon said standard, the

1 standard 9 has a lateral arm1 10- atabout its middle to which the core piece of' one of the pair of the magnets -3 -'is fastened. The other magnet of. the pair; is built up around thestandard itself, and said standard -9- has a transverse f 'o'pen'ing -12- above the said coils the inner end of armat ire i lfi, suspended at this point magnets by a fiatspring be'nt orbowed upar-area: one endliy wi' hj'itis it'astened to are other Sa Standa d y 9 knowng'that w'e, CHRrsTIAN REINKER and lVI A a REINKER,'C1UZQI1S of the Unlted Letterslatent.

aer m od t material'placed about the fastening screw -17- which secures said plates in place. Screw -'7 has threaded engagement with both plates 15, and when screwed therein the ends of the plates are sprung apart-from eachother to provide a spring locking aetion upon the threads engaged and thereby lock the screw firmly in any adjusted posi' tion, thus dispensing with lock nuts such as usually employed to prevent disarrangement oflthe contact point as set. Bell 8 is re movably mounted'upontop of standard 9 byscrew 18. v The device as described up to thispoii it will operate to ring bell '8- in full strength bya vibratory movement of liam toclose the electric circuit a in which' mag nets -'3- are connected and as diagram} matically shown in Fig. 1. Now, in order to obtain alarms having distinctly difieije'nt with the main alarm mechanism. Thug, in one instance, hammer 5-' ,islwithlielgl 'fromlstriking bell 8--and restricted'ii'n its vibratory, -inovement so as to stance bell 8 is deadened in tone pressing a cushioning member, against it during the-strokes by hammer ';5 he meailsto thisend comprise two magnet op angles to come opposite armature -'--2 impart merely a buzzlng' sound, and in another in piece 21 secured tds'tantlard which is'pivoted to cars on standard 9 Patented Dec. 1, 1908;

To bring this action under I'ttljtlziittblt! control, stem 2o has a shoulder or enlargement 15?, and arnniturc 2?)- has a set screw 25 at its end which is adapted to engage the said shoulder when opposite thertao, as when the armature is down. Magnet so is energized when push button it closes the circuit over line b and which brings magnets -lalso in circuit, 'lhus, magnet no is electricall y connected in parallel with magnets and a shunt is pro\ idcd through spring iland contact piece --2t)-- to maintain a circuit for make and break operations of magnets -3-- in line a. 'lhus the current is divided between the magnets -2tl--- and 25-, re-

spectively, without allfecting the operation oi either during the time push button B is pressed to close the circuit to operatethe device as a buzzer signal or alarm.

l\'ow re'l'erring to push button ---C and the corresponding device for changing the ringing toii'e of hell -8--, we employ a small magnet -30" mounted onupright core 2) t--- extending from base -2- amt arrange an armature -32-- above the same by pivoting it on a post also supported on base -i3- but insulated theretrom. Armature -32 has an arm ---3stat one end which is bent at an angle thereto along parallel lines with the adjacent wallet bell -t5-. A felt or other cushioning strip or segment --;--;'5i-- is mounted at the end of arm ilt and is adapted to press against the bell and thereby deaden amt change its tone when armature -32 is actuated by magnet 30. This occurs when push butten 0 is pressed and a'circuit. established over line a in part and over line (1 connected with magnet -30 and post 3?,---. \Vlicii magnet -30 is cnergized,.armature 32 is attracted and contact is made between an end part 7-- on the z'irn'iature and a Statienary contact member ith coi'incett-id by line r[ to line it, therchv plat-inn; magnet --3tlin'parallel circuit with nnn,:nets--Z-5--- and providing a con tant circuit for i'nag'i'iet Ill --durin;;' make amt break operations of magnets -I";

.liavin; thus d 4--'crilied the d vice in its entirety, it is plainly seen that either of the three push buttons, A, B or C, may be used to close an electrical circuit to operate the call-bell, and in each and every event, the bell hammer, -5- will be vibrated to sound an alarm. llowever, the sounds produced will he dilt'erent in tone or character ilependent upon which button is selected and pressed, or to be more exact, dependent upon whether the main call magnets --3- are energized alone or in combination with either ot the two auxiliary magnets -E20-- and ---Z3tt--, respectively, which have a supplementary control of the bell hammer --5- and the bell -8-.
